Cheers, all that info on the api's isn't strictly needed but I thought it good background so people understood why things only work when stuff is setup in a certain way.

On Winodws simply upgrading from Eden to Frodo may mean that previously working OS settings are no longer any good for AudioEngine in Frodo and stuff will no longer work. Credit for the api info goes to DDDamian, I've just re-worked it slightly to try and make it more readable.

Something I'm not sure is appropriate for the FAQ or maybe on the AudioEngine pages is the graphics vendor specific info for Linux, I don't use Linux but having tried to follow all the AE main threads it's my belief that:

ATI/AMD HDMI outputs only support 2 channel PCM and 5.1 for the compressed formats like DD & DTS, they do not support multichannel PCM or the HD Audio formats due to a limitation of the ATI/AMD fglrx drivers.

Intel had a problem with their drivers too not working with the HD Audio formats, Intel made a patch but not sure if that made it into the Linux 3.7 kernel. This could still be a problem couldn't it if people have an old kernel version? What about XBMCbuntu? I'm assuming that will include the patch in some form?

XBMCbuntu is notoriously bad for drivers all around. and version v12 is no better.

I agree that drivers should be part of the FAQ just not part of AE topic in detail cause its video drivers even if they do affect audio. Maybe adding it to wiki as a reference to a bigger topic. AFAIK I only know NVidia part. though a AMD bit can be added to point to relevant forum discussion.

It might be good to just start a page/section of the wiki just for GPU hardware to cover those topics, and have lead-in links/sections from the FAQ, AE page, etc. That way we can reference it from multiple places on the wiki.

Yes agreed but I cant rename pages, so we need a Jedy. Ive done a few more bits so links to forums and updated info + ton of stuff. This windows ae settings page is referenced already, if name changes the references need updating as well.

I'm kinda new around here so don't like to just jump in and start doing things..But I had a bit of trouble getting AirPlay to work on my Windows PC. Eventually sorted - had to open Port 36667 on Windows Firewall. I don't know if it would be worth adding this to the FAQ? http://wiki.xbmc.org/index.php?title=AirPlay

As I don't know Linux well & follow the Linux developments closely I don't know if the patches made it into Linux kernal 3.7 and what kernel XBMCbuntu is using.

If users are going to have to compile the patch to get HD Audio working on Intel then it would be good if someone with some know how documents the problem & solution, it's not something I'd feel comfortable doing with my limited knowledge.
